jit.qt.movie and jit.qt.record

Question 1:
I am trying to let jit.qt.movie RANDOMLY open one quicktime movie from a list of movies stored in one folder in the computer hard drive, which I send the READ message to jit.qt.movie

Question 2:

I am also trying to let jit.qt.record record the clip directly to a folder in the harddrive when I send the WRITE message to jit.qt.record
For example, the first time I hit WRITE message, movie 01.mov will be saved. The second time I hit WRITE message, movie 02.mov will be saved, etc.

Again,while learning [folder] object, there is a TYPES message that I can send to [folder] to specify the types of the file to show in the [umenu] connected to [folder]. What is the message for .mov file? e.g. .txt file is TYPES TEXT, maxmsp patch file is TYPES JSON

Thank you all. I got it working.
However, while I was using [sprintf], I tried [sprintf "Mac Harddrive:/Users/Desktop/%lb.mov"] and feed the result to message {write $1}. The quote mark " " is not showing when I feed the message. I could not figure out why? Without the quote mark " ", message {write } can not recognize the path for the file.
Any one knows how to fix this?

Greetings,
I’m trying to do something similar but having trouble understanding how to set it up.
Here’s a link to my post. Can anyone post a sample patch so I can see how this done?
It would be greatly appreciated.
